The XRF080109-SN2008D and a decade of GRB-Jet-SN connection

TL;DR

This paper reviews a decade of research on gamma-ray bursts (GRBs) and supernovae, proposing that jets from supernovae powered by black holes or pulsars explain various observed phenomena including XRFs and orphan GRBs.

Contribution

It introduces a unified jet model for GRBs and supernovae, explaining diverse observations through precessing, spinning gamma jets with specific emission mechanisms.

Findings

Supernovae often contain jets that can produce GRBs.

XRFs are peripheral viewing angles of the jets.

Jet precession and decay explain GRB variability and afterglow durations.

Abstract

Last and nearest GRB-XRF 080109 has been an exceptional lesson on GRB nature. After a decade (since 25 April 08) we know that Supernovae may often contain a Jet. Its persistent activity may shine on axis as a GRBs. Such a persistent, thin beamed gamma jet may be powered by either a BH (Black Holes) or Pulsars. Late stages of these jets may loose the SN traces and appear as a short GRB or a long orphan GRB (depending on jet angular velocity and view angle). XRF are peripherical viewing of the jets. These precessing and spinning gamma jet are originated by Inverse Compton and-or Synchrotron Radiation at pulsars or micro-quasars sources, by ultra-relativistic electrons. These Jets are most powerful at Supernova birth, blazing, once on axis, to us and flashing GRB detector. The trembling of the thin jet explains naturally the observed erratic multi-explosive structure of different GRBs. The jets are precessing (by binary companion or inner disk asymmetry) and decaying by power on time scales of few hours, but they keep staying inside the observer cone view only a few seconds duration times (GRB); the jet is thinner in gamma and wider in X band. This explain the wider and longer X GRB afterglow duration and the rare presence of X-ray precursors.
